This inventionrelates to a reclining chair an d concerns itselfprim'arily with means foi' adjusting the combined leg frest and foot rest so that the same'will foi' the/occupant.

lThe inventioncomprises "the novelstructure and combinationof parts hereinafterde Y scribed fand more .particularly pointed out and Y defined in the appended claims.

In the accompanyingdrawings, which 'illustrate a Aprefer'red form of this invention and in which "similar reference nurnerals re` fer to similar features in the dilferent views: Figure 1 is a front elevational view of a reclining chair involving this invention;

Figure 2 is a side elevational view of the chair. Y Y

Figure 3 is an enlarged fragmentary sectional view showing parts in elevation.

Figure 4 is an enlarged rear plan' view of the leg rest and foot rest in extended position.

Figure 5 is an enlarged fragmentary sectional view taken substantially upon the line V-V 0f Figure 3.

Figure 6 is a sectional view taken upon the line VI-VI of Figure 4.

Referring to the drawings, it will be noted that the illustrated 'chair-comprises the usual pedestal 1 which supports the seat yrail 2 which is'ordinarily rotatable, and which supports the cushion 221 which in the present instance is not connected'for a sliding movement as is common in barber chairs. A pair of brackets 3 (only one of which is shown) extend from the seat rail. The reclining back 4 of the chair is provided with two armed castings y5; one arm of each casting is pivoted to a bracket 3, while the other arms are pivoted to always be :comfortable hangers `13.

A' socket member 19'is keyed upon the aforementioned rod 12 between the arms ofv the bifurcated bracket 10. A rod 2O extends; from the socket member 19 and passes` through a clamp 21 shown in Figure` 5.1' The a movable member 21" which is normally held y in operative position by aA spring 22. The

clamp 1s adapted to be released by' a lever 23 the arm rests 6 which are usually covered with' lpads 6a.V It will be noted that the back has no connection with the cushion 2a. The forward ends of the arm rests are pivoted to the upper also has no connection to the cushion 2a. These side bars are pivoted intermediate their ends to brackets3a rising from'the seat rail.

The leg rest Sis provided with` a pair of rearwardly extending brackets 9 and an intermediate bracket 10. A The terminals of the brackets 9 in connection with removable straps 11 form bearingsV for a shaft 12. The

. bracket l10 is provided with a bifurcated terminal, the arms of which also 'serve as bear-r ings lfor the shaft 12 as shown in Figure 4. yIt will hence loe apparent that this inven- Vends of the side bars 7 of the lleg rest 8, which connectedv to a form of toggle 24 engaging the movable clamp member. This clamping mechanism is, however, old and well-known and` forms no part of this invention except as 1t may cooperate therewith.

l/Vhen the rod 20 is released from the clamp, vthe back 4 of the chair maybe tilted rearwardly to inclined position. During such movement of theback yof the chair, thel leg rest 8 will pivotv upon the brackets 3@ to the position shown in dotted liriosv in Figure 3, the rod 20 sliding in and pivoting withy its mounting. During this movement of the legV rest the foot rest 17 will of course be carried therewith, but on account of the pivotal connection of the inclined arms of the foot rest 'with the "bars 14, said foot rest will have a'y 'turning movement with respect to the leg rest as it is beingraised. This turning movement is,however, lcontrolled Vby the bars 14 so that it'will be raised in Vsubstantially horizontal*A position and'will remain inl/such position 'Y Y when the leg rest is fully elevated. This operation arises from the fact that the socket'lt) and bifurcated arms 13` are keyed upon the shaft 12 vand bars 114 must actas radius rods with respect to their pivotal supports. l

' tion provides mechanical means for automati ically controlling the foot rest and maintaini ing the same horizontal during the elevating movements of the leg rests, and aftergthe elevation thereof. In the past'thesefoot rests have generally Vbeen manually adjusted.

` The combined foot restV and leg rest have the proper relation in all positions of adjustment toeafford the most comfort vfor the occupant of the chair.
